Answer:

The answer is: Electrostatic forces.

Explanation:

The chemical structure of a chemical substance provides information on how the different atoms or ions that form a molecule, or atomic aggregate, bind.

Intermolecular forces or junctions are those interactions that hold the molecules together.

Intramolecular forces correspond to interactions that hold atoms together in a molecule.

It is electrostatic forces.

The answer is: Electrostatic forces.

a car takes off from rest and covers a distance of 80m on a straight road in 10s.calculate the magnitude of its acceleration

Here's the solution :

Let's find the final velocity :

$\dfrac{displacement}{time}$

$\dfrac{80}{10}$

$8 \: \: ms {}^{ - 1}$

Initial velocity (u) = 0 (cuz it started from rest)

Final velocity (v) = 8 m/s

Time taken (t) = 10 sec

now, we know that :

$acceleration = \dfrac{v - u}{t}$

$\dfrac{8 - 0}{10}$

$\dfrac{8}{10}$

$0.8 \: \: m {s}^{ - 2}$

Acceleration = 0.8 m/s²

Scilla [17]

Answer:

D. 24 m

Explanation:

Running up - velocity + 30 m/min

Escalator 's moving down velocity - 24 m/min

Sum velocity (30 - 24) = 6 m/min

6 m/min * 4 min = 24 m

A sound wave, generated at a frequency of 440 hertz has a wavelength of 2.3 meters as it travels through a solid material. The a

Jlenok [28]

The approximate speed of the sound wave traveling through the solid material is 1012m/s.

<h3>Wavelength, Frequency and Speed</h3>

Wavelength is simply the distance over which the shapes of waves are repeated. It is the spatial period of a periodic wave.

From the wavelength, frequency and speed relation,

λ = v ÷ f

Where λ is wavelength, v is velocity/speed and f is frequency.

Given the data in the question;

Frequency of sound wave f = 440Hz = 440s⁻¹

Wavelength of the wave λ = 2.3m

Speed of the wave v = ?

To determine the approximate speed of the wave, we substitute our given values into the expression above.

λ = v ÷ f

2.3m = v ÷ 440s⁻¹

v = 2.3m × 440s⁻¹

v = 1012ms⁻¹

v = 1012m/s

Therefore, the approximate speed of the sound wave traveling through the solid material is 1012m/s.
